OLLA CLEANING MACHINE 2 Sheets-Sheet 1 Filed March 6, 1951 win I Sept. 27, 1932. F. P. BUCKLEIN OLLA CLEANING MACHINE Filed March 6, 1951 2 Sheets-Sheet 2 Patented Sept. 27, 1932 UNITED STATES FRANK P. BUCKLEIN, OF LOS ANGELES, CALIFORNIA OI'LA CLEANING i MACHINE Application filed March 6,

This invention relates to an olla cleaning machine designed to be used for cleaning ollas such as those which are employed in drinking water dispensers. Ollas which are used for this purpose in the course of time i have deposited thereon certain lime deposits. Also there. are other sedimentary deposits which should be cleaned from the olla from time to time.

An object of the present invention is to provide a machine which will rotate such an olla in such a manner as to permit the interior of the olla to be thoroughly cleaned as well as the exterior thereof. 7

As these ollas are formed of fired clay products they seldom are of uniform size and shape. In fact most ollas are slightly warped due to the firing and an object of the present invention is to provide a construction which will efficiently handle such ollas even though they may be warped. 1

With the foregoing and other objects in view, which will be made manifest in the following detailed description, and specifically fiiT-ipointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Fig. 1 is a top plan View of the improved aeiolla cleaning machine.

Fig. 2 is a View in side elevation of the same. 7

Fig. 3 is a view in end elevation of the olla cleaning machine.

Fig. 4c is a sectional view taken substantially upon the line 4c4 upon Figure 2.

Fig. 5 is a sectional view taken substantially upon the line 5-5 upon Figure 1.

Fig. 6 is a sectional view taken substan- 4 tally upon the line 66 upon Figure 5.

Referring to the accompany drawings, wherein similar reference characters designate similar parts throughout, the improved. olla cleaning machine comprises a suitable 4 fra'me 10 on top of which is mounted a cleaning basin or chamber 11, preferably having an open top. On one side of the frame 10 there is rotatably mounted a shaft 12 suitably supported in bearings 13 and 14. This shaft carries a sprocket 15 and one end of the shaft 1931. Serial No. 520,729.

extends into the cleaning basin 11 and carries a rotatable plate 16 which is bolted or otherwise secured to the shaft. In direct opposition to shaft 12 there is a second shaft 17 which is supported in bearings 18 and 19. 165

This shaft is capable .of longitudinal movement as well as rotation and is provided with a sprocketQOof the same size as sprocket 15. Sprocket 20 has asplinedconnectionwith shaft 17 and is providedby a key 21 which is slidable in a keyway 22 in the shaft. Twospaced collars 23 and 24: are rigidly fastened to the shaft and form shoulders between which there is a screw 25. Screw 25' is held against rotation by a key 26 fastened "to bearing 27.' This key is longitudinally slida'ble-in a keyway 28 formed in the screw. The screw is preferably provided with square threads so that the tops of the threads will form' sufficient bearing surface for engagement with the interior sur face of bearing 27. A hand: wheel 29 is threadedly mounted on the screw and carries a sleeve 30 surrounding the screw. A coil spring 31 is compressed between the hand wheel and a collar 32 disposed about the sleeve 75 and held in position by supporting brackets 33 mounted on bearing 18. The end of shaft 17 extends into the cleaning basin 11 and carriesa conical head 34 of such size as to partially enter the neck end of the olla 0. Bearings 35 and 36 serve to rotatably support a line shaft 37 below the cleaning basin 11 and this line shaft carries a pair of sprockets 38 and 39 which are of equal size, which are con nected to sprockets 15 and 20 by chains 40 and ll. The line shaft also carries a sprocket 42 over which extends a chain 43 enabling the line shaft to be driven by a motor 44:. In this manner both shafts 12 and 17 will be driven at the same speed of rotation by'the motor 44:. The reference character 45 designatesa suitable drain leading from the bottom of cleaning basin 11. 5 The operation of the improved olla cleaning machine is as follows. The olla O is insertcd in the basin 11 with its bottom positioned against the-face of plate 16. Rotation of the hand wheel 29 causes screw 25 to be advanced. The screw 25' bearing against collar' 23 causes shaft 17 to be advanced, this mtiolla is limited to the force capable of being longitudinal sliding movement being allowed to take place by virtue of the splined connection between sprocket 20 and the shaft 17. The shaft 17 is sufliciently advanced by the hand wheel to cause the head 34 to engage the neck end of the olla. The force with which the head 34 can engage theneck of the olla is limited to a predetermined amount so that there is no danger of tightening the construction to such an extent as to break the olla. This is accomplished by thepresence of spring 31 which urges hand wheel 29 into engagement with the end of bearing 27. 'However, when the olla is engaged by the head 34 and the hand wheel 29 is given further rotation, it does not advance the shaft 17 and head 34 but instead merely backs up on screw 25, compressing coil spring 31. In this manner the force with which the head 34 can engage the exerted by spring 31. Vith the olla thus positioned between the rotating members 16 and 34, the motor 44 can be started to drive shafts 1'2 and 175andv thus rotate the olla. sDuring'the' rotation the exterior of the olla may be scrubbed with wire brushes or any other cleaning agent and the interior of the olla is cleaned by placing'gravel, shot, metal chips, or other abrasive, in the olla prior to ?its being mounted on the machine. During the; rotation the'abrasive on the inside of the olla is tumbled, effectively cleaning the inside of the olla. \Vater used in the cleaning operations is effectively drained from the basin "by drain pipe 45.

From the above described construction it will-be appreciated that a novel advantageous ollacleaning machine is provided which will effectively clamp the olla in a horizontal position and cause its rotation. The machine is so designed that it will handle ollas which are not of uniform size and the presence of the olla so that there is no danger of breaking it on mounting the olla on the machine.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.

I claim: r 1. An olla cleaning machine comprising two opposed rotary shafts, members on the ends of the shafts adapted to have an olla positioned therebetween, means for rotating one of the shafts, the other shaft being longitudinally movable, a screw having a swiveled connection between shoulders on saidother shaft, means for holding the screw against rotation, a hand wheel threaded onto the screw, and spring means urging the hand the opposite longitudinally movable rotary shaft opposite the plate, an olla engaging member carried thereby, a screw arranged between shoulders on the shaft and within which the shaft rotates, means for holding the screw against rotation, a hand wheel threaded onto the screw, and means yieldably urging the hand wheel, screw and shaft into a position in which an olla will be engaged by the member on the end of the shaft.

3. An olla cleaning machine comprising a cleaning basin, two aligned shafts arranged on opposite sides of the cleaning basin, members on the ends of the shafts and within the cleaning basin adapted to engage an olla placed therebetween, a screw having a swiveled connection with one of the shafts but holding against sliding relatively thereto, means for holding the screw against rotation, a hand wheel threaded onto the screw, spring means urging the hand wheel, screw and shaft into olla engaging position, and means for driving both shafts at the same speed of rotation.

4. An olla cleaning machine comprising two opposed rotaryshafts, members on'the ends of the shafts adapted to have an olla positioned therebetween, one shaft being longitudinally movable, a screw having a swivel connection between shoulders on the longitudinally movable shaft, means'for holding the screw against rotation, 'a hand wheel threaded onto the screw, means urging the hand wheel, screw and shaft toward the opposite shaft, and means for rotatingsaid longitudinally movable shaft.

In testimony whereof I'have' signed my 4 name to this specification.
